Abstract
In a coupling arrangement for use in a textile machine, a drive shaft can be intermittently rotated and a connecting member encircles and is connected to the drive shaft by an eccentric hoop located between them. A coupling key is displaceable between a coupling recess associated with the drive shaft and a coupling recess associated with the connecting member. The coupling key is retained in the recesses by lead cams. A shifting ring displaces the coupling ring alternately between the coupling recesses. The shifting member can be pivoted between two positions and a spring biases it into one of the positions. A control device moves the shifting member between its two positions. The control device includes a rotatable shaft with a rocking lever fixed to it. The rocking lever engages the shifting member for moving it from one position to the other against the biasing action of the spring. The control device includes a control part and based on the state of the control part the shifting member can be moved or held in place. The rocking lever performs one reciprocal motion for each cycle of a shedding unit and, accordingly, during each cycle the control of the shifting ring is effected …
